Purpose:

RATIONALE: Monoclonal antibodies, such as rituximab, can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Drugs used in chemotherapy, such as cyclophosphamide, doxorubicin, vincristine, and prednisone, use different ways to stop cancer cells from dividing so they stop growing or die. Oblimersen may increase the effectiveness of a chemotherapy drug by making cancer cells more sensitive to the drug. Combining oblimersen with rituximab and combination chemotherapy may kill more cancer cells. PURPOSE: This phase I trial is studying the side effects and best dose of oblimersen when given together with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone in treating patients with stage II, stage III, or stage IV large B-cell lymphoma


Study summary:

OBJECTIVES: Primary - Determine the feasibility and safety of oblimersen administered in combination with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone, in terms of short-term and long-term toxicity, in patients with previously untreated stage III or IV or extensive or bulky stage II diffuse large B-cell lymphoma. - Determine the maximum tolerated dose of oblimersen administered with this regimen in these patients. Secondary - Determine the remission rate and failure-free, progression-free, and overall survival of patients treated with this regimen. OUTLINE: This is a nonrandomized, non-blinded, multicenter, dose-escalation study of oblimersen. Patients receive CHOP-R* therapy comprising cyclophosphamide IV over 15-45 minutes, doxorubicin IV over 5-10 minutes, vincristine IV, and rituximab IV over 30-90 minutes on day 1 and oral prednisone on days 1-5. Patients also receive oblimersen IV continuously on days -4 to 3. Treatment repeats every 21 days for 6-8 courses in the absence of disease progression or unacceptable toxicity. Patients who discontinue treatment due to unacceptable toxicity to oblimersen may continue to receive standard therapy comprising CHOP-R. NOTE: *Patients treated at the British Columbia Cancer Agency receive cyclophosphamide, doxorubicin, vincristine, and rituximab on days 1 and 2 and prednisone as above. Cohorts of 3-6 patients receive escalating doses of oblimersen until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. Once the MTD is determined, at least 10 patients are treated at that dose level. Patients are followed every 3 months for 2 years, every 4 months for 1 year, every 6 months for 2 years, and then annually thereafter. PROJECTED ACCRUAL: A total of 19-28 patients will be accrued for this study within 5-10 months.
